Stack, I think fixing the tests is more appropriate way to go. I have found out that at least another change affects the tests, e.g
The method getWriterFactory(Configuration, CacheConfig) in the type HFile is not applicable for the arguments (Configuration)
I am looking through the history to find where the change has happened to open another ticket.
If you guys can fix the tests - that'd be great. If there're no spare cycles on your side - I will be working on it later in the day.
